Provides T3 directly.

The thyroid primarily produces T4, which the body converts into T3.

Liothyronine provides T3 directly to help restore thyroid hormone activity in people with hypothyroidism.

It may be used alone or, in selected patients, alongside levothyroxine as part of an individualized thyroid treatment plan.
